Description

Calcium ionophore I is a Ca²⁺-selective ionophore for biological membranes that can be used in microelectrodes for the determination of intracellular Ca²⁺-activities and of slowly changing Ca²⁺ levels.

Purification Methods

This is a neutral Ca selectophore. It can be purified by thick layer (2mm) chromatography (Kieselgel F245) and eluted with Me2CO/CHCl3 (2:1). [Ammann et al. Helv Chim Acta 56 1780 1973, Simon & Carafoli Methods Enzymol 56 439 1977.]
